Astana (the former Akmola) was founded in 1830 as a fortification of Russian Empire. In 1862 stanitsa Ak-mola got the status of a town. In the course of time Akmola became the centre of trade fairs where merchants from all over Kazakhstan. Russia, Central Asia, India and other countries gathered to sell cattle and agricultural products. For a long time Akmola was an outpost of Russian Empire seeking the way to developed trade and its political influence upon Central Asia in XVIII-XIX centuries. With the growth of anti – tsarist and revolutionary public mood the Akmloa prison became over crowed with those who wanted freedom. In March 1917 the Soviet Power was established in Akmola.

Many changes have taken place since then. Akmola played an important role in supplying the Soviet Army with raw materials and products during the Second World War. In 1961 Akmola was renamed into Tselinograd and became the centre of Tselinny Krai. In 1992 the city got its name Akmola again and sice October 1997 Akmola has become a new capital of the Republic of Kazakhstan. Later on it got its present name Astana. Astana is a modern growing city, a political, financial, economic, scientific and socio-cultural centre of the state. There are a lot of magnificent beautiful buildings, higher educational establishments, colleges and secondary schools, hotels, banks and other commercial structures in Astana, the new capital of the Republic of Kazakhstan. There are many places of interest in Astana: the Central Square the Republic Avenue, the Palace of Youth and the Bridge across the Ishim River, the Reginal Museum of Fine Arts and others. From everywhere you can see Baiterek, the symbol of prosperity and happiness.
